The number of exercise variations can range from zero (exhibit A: the Bulgarian national weightlifting team) to a hundred (exhibit B: the Soviet national weightlifting team).
According to Mark Reifkind, StrongFirst Certified Master Instructor Emeritus, five or fewer variations per lift hit the spot for most trainees, including serious lifters. This is the StrongFirst standard.
There are many ways to program these “same but different” exercises. Change them: From set to set After several sets From day to day Every 6 weeks
Prioritize variations that address your weaknesses and/or improve your technique.
E.g., you are lacking tightness in your weighted pullups. Instead of attaching weight to a belt, hang a kettlebell on one foot and cross your ankles. Your abs will contract whether they like it or not.
Medical professionals who work with lifters often use specialized variety to treat minor injuries. They choose exercise versions that do not hurt and allow the greatest safe range of motion. As Eastern European strength athletes say, “pump through an injury.”
Some years down the road circumstances may force you to replace some exercises, temporarily or permanently. Until then, carry on. |
